  • the contact pressure is applied to the area where the anti slip portions 8 are provided, so that sufficient grippability at the front holding portion can be obtained.
  • the grippability can be increased, making it possible to provide the shaver 1 which is hard to slip during use and has the main body 2 that is easy to use.
  • the razor 6 head portion 3 contacts the skin at an optimum angle, so that the time to shave can be shortened.
  • the anti slip portion 8 provided on the upper half part 2C U of the back 2C of the main body 2 serves simultaneously as a trimmer operation portion 70a.

  • the trimmer operation portion 70a Since the trimmer operation portion 70a is positioned in the vicinity of the upper bent portion 2b of the substantially S-shape in such way, the trimmer operation portion 70a functions as a finger contact portion when hairline-shaving by a trimmer.
  • the trimmer operation portion 70a When performing trimming operation, in the case of either the "gripping and holding” or the “pinching and holding", it is possible to stably to hold the shaver 1 at a position near the head portion 3 by holding it in such a manner as to position the thumb right on the back side of the upper bent portion 2b of the substantially S-shape of the shaver 1.
  • the trimmer operation portion 70a provided with the anti slip portion which functions as a finger contact portion, contacts the thumb, so that up and down operation of the trimmer operation portion 70a can be easily performed by the thumb without slipping.

Further, in the trimmer block 70, the anti slip portion 8 is provided on the trimmer operation portion 70a (the upper part 2C U of the back 2C) at substantially the same height as the anti slip portion 8 of the upper part 2A U of the front 2A of the main body 2. Thereby, the holding force by the thumb from the front 2A of the main body 2 gets in balance with the holding force by the index finger and the middle finger from the back 2C.
  • the end podite of the thumb contacts with the anti slip portion 8 of the upper part 2A U of the front 2A of the main body 2, while the base podite 25 and the middle podite 29 of the index finger contact with the anti slip portion 8 of the trimmer operation portion 70a of the trimmer block 70, respectively.

  • the head portion 3 broadly divided, comprises a head case block 74 containing a linear motor 73, inner blades 5 and an outer blade block 75.
  • the vibration of the linear motor 73 in the X-direction is transmitted to the inner blades 5 by driving elements 13 at top ends thereof. Due to the sliding of the inner blade 5 and the outer blade 4 on each other, the beard introduced into meshed blade holes of the outer blades 4 is cut off.
  • the linear motor 73 is inserted from above into a head case 77 in a state of being integrally coupled at its lower end to a motor base 76, and is fixed from below with head lower screws 78.
  • a head case cover 79, a driving element waterproof rubber 80 and a rubber pressure plate 81 are fixed, in order from below upward, to the head case 77 with head upper screws 82.
  • the head case block 74 is formed to be one housing having the linear motor 73 built therein.

  • Lead wires 83 extending from below the linear motor 73 are to be connected at their ends to a driving circuit in the main body 2 in order to drive the linear motor 73. Hence, they pass through a hole (not shown) provided in a lower portion of the head case 77, and are inserted into and passed through a waterproof rubber tube 85, as shown in FIG. 24 . They further pass through a hole 87 (refer to FIG. 27 ) provided in an upper surface of a later described front housing 86, and are connected to a circuit 84 in a box-like space 110 of the main body 2, which consists of a front housing 86 and a back housing 89.

Accordingly, the head portion 3 can relatively widely move relative to the main body 2. Furthermore, since the head portion 3 and the main body 2 are waterproof, the inner blades 5 can be washed with water, thereby cleanability is increased.
  • a protruding portion 77a is formed in a manner so that it protrudes downward and decreases its width in the X-direction.
  • the protruding portion 77a is supported to be swingable relative to a front wall 86a and a back wall 89a (refer to FIG. 24 ) of the main body 2, so that the head portion 3 can be swung on the X-Z plane relative to the main body 2, making it possible to increase the followability of the head (sic: correctly head portion) 3 to the skin.
  • a gap is produced between the lower part of the head portion 3 at its both ends in the X-direction and the upper end of the main body 2, so that it becomes easier to check the movement of the head portion 3 when shaving. Furthermore, as shown in FIG. 20A , since a width dimension L 2 of the upper part of the main body 2 in the X-direction is made larger than a width dimension L 1 of the front wall 86a and the back wall 89a, the probability for a finger to enter the movable range of the lower side of the head portion 3 in a normal gripping state decreases significantly. Thereby, it is possible to realize a configuration to secure the grippability with fingers being prevented from contacting the head portion 3 and not to impede the movement of the head portion 3.
  • the mechanism to hold the head portion 3 in the Y-direction is provided on the front wall 86a.

Accordingly, even if there are variations in pitch between the front wall 86a of the front housing 86 and the back wall 89a of the back housing 89, the head case block 74 is latched to the front wall 86a, thereby preventing the rattles in the Y-direction.
  • a projecting portion 90 is provided to extend downward from a lower back part of the head latching member 88.
  • This projecting portion 90 is in sliding contact with an inner surface of the back wall 89a, so that the head case block 74 is prevented from tilting in the Y-direction. That is, the head case block 74, in a state of not tilting in the Y-direction, is guided only in the Z-direction due to the sliding contact of the projecting portion 90 with the inner surface of the back wall 89a of the back housing 89.
  • the head portion 3 does not tilt in the Y-direction, so that it can be prevented from becoming difficult to shave due to tilting of head portions as in conventional shavers.

  • a force to lower the head portion 3 downward is generated, with both ends of the head portion 3 being in contact with the skin.
  • the fulcrum of the rotation of the head portion 3 increases its distance from the force point because the head support member 43 on a side opposite to the side contacting the skin serves as an axis, thereby the force to rotate the head portion 3 is increased.
